Gassing Mechanism and Stability of Foamed Explosive Emulsions. Mining of minerals such as coal involves crushing the surrounding rock strata, or the mineral ore itself, with emulsion explosives. One of the most important properties determining suitability of an emulsion explosive to a particular mining operation is its velocity of detonation, which can be adjusted by varying the number and size of air bubbles distributed in the emulsion matrix. The present project aims to develop new ways of g ....Gassing Mechanism and Stability of Foamed Explosive Emulsions. Mining of minerals such as coal involves crushing the surrounding rock strata, or the mineral ore itself, with emulsion explosives. One of the most important properties determining suitability of an emulsion explosive to a particular mining operation is its velocity of detonation, which can be adjusted by varying the number and size of air bubbles distributed in the emulsion matrix. The present project aims to develop new ways of generating air bubbles, to gain fundamental understanding of the foaming mechanism in currently used gassing techniques, and to invent ways to stabilise large bubbles within the emulsion. The project will provide scientific underpinning for the development of a new range of emulsion explosives manufactured by Orica for Australian and international markets, maintaining the Orica's position as a leader in the field of emulsion explosives.Read moreRead less
Role of Reactive Particles in Explosive Emulsions. Concentrated water-in oil explosive emulsions are widely used in the minerals industry because they are cheap, easily detonated and relatively safe to handle. Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and ch ....Role of Reactive Particles in Explosive Emulsions.

Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and chemical interactions that occur between the particle and the oil-water interface, and develop a more efficient explosive that can be produced continuously on a commercial scale.Read moreRead less

Many chemical reactions occurring in solid materials during heating significantly affect the materials' stability, and subsequently affects the processes of production of clean energy, material synthesis, catalyst preparation, and nanotechnology. No equipment currently exists in Australia that will mitigate the wide range of conditions in such reactions in materials processing. This situation impedes research progress in Australia, disadvantages Australian research students, and ultimately makes our research less competitive internationally. The establishment of the proposed apparatus will increase the competitiveness of Australian science and engineering, and contribute to the development of new Australian technologies that are important to the Australian economy and to environmental sustainability.Read moreRead less

With the pressing need for the reduction of Greenhouse emissions from electricity generation in Australia, one option that must be seriously considered is nuclear energy. However, the issue of waste storage is a highly significant one that must be addressed. Geopolymeric cements are expected to perform much better than traditional Portland cements in nuclear applications, both for solidification of radioactive wastes and also for the construction of underground waste storage bunkers. This project will use Australia's strong existing knowledge in geopolymers research, and apply it to the development of materials to fill the need for environmentally secure waste storage solutions.Read moreRead less
